Wow! Virgil, you put a lot of work into that.
BTW I just chose to open the file in Excel and it opened fine.
I make my own bidding spread sheets as well. Wonder if you have considered using separate sheets for each of your rooms and then post the room info to a last page summary sheet.
You could also have a "general conditions" sheet for any oddball items ,say, temp power, travel etc.
Whatever, looks great, Kent
